On Earth, we are unmanned by our longing for a pastoral past that never really existed; and that, if it had existed, could never exist again...on the Moon, there is no past to long for or dream about. There is no direction but forward.

Isaac AsimovTo all my gentle readers who have treated me with love for over 30 years, I must say farewell. It has always been my ambition to die in harness with my head face down on a keyboard and my nose caught between two of the keys, but that's not the way it worked out. I have had a long and happy life and I have no complaints about the ending, thereof, and so farewell - farewell.
Isaac Asimov
